In the following description, various embodiments according to the present invention are explained with reference to attached drawings.

FIG. 1 is a schematic diagram illustrating a service system including a digital device according to one embodiment of the present invention.

Referring to FIG. 1, examples of a service system comprising a digital receiver may include a content provider (CP) 10, a service provider (SP) 20, a network provider (NP) 30, and a home network end user (HNED) (Customer) 40. The HNED 40 includes a client 100, that is, a digital device.

The CP 10 produces and provides content. Referring to FIG. 1, the CP 10 can include a first or second terrestrial broadcaster, a cable system operator (SO), a multiple system operator (MSO), a satellite broadcaster, various Internet broadcasters, private content providers (CPs), etc. The CP 10 can produce and provide various services or applications as well as broadcast content.

The SP 20 service packetizes content provided by the CP 10 and provides to FINED 40. For example, the SP 20 packetizes at least one content provided by the first or second terrestrial broadcaster, the cable SO, the MSO, the satellite broadcaster, various Internet broadcasters, the private CPs for service and provides it to the HNED 40.

The SP 20 can provide services to the client 100 in a uni-cast or multi-cast manner. Meanwhile, the SP 20 can transmit data to plurality of clients which are previously registered at once, and Internet Group Management Protocol (IGMP) may be used in transmission.

The CP 10 and the SP 20 can be configured in the form of one entity. For example, the CP 10 can function as the SP 20 by producing content and directly packetizing the produced content into services, and vice versa.

The NP 30 can provide a network environment for data exchange between the CP 10 and/or SP 20 and the client 100.

The client 100, a consumer included in the FINED 40, can construct a home network, receive data and transmit/receive data for various services or applications such as a VOD, a streaming, and the like, via the NP 30.

The CP 10 and/or SP 20 included in the service system can use a conditional access or a content protection means for protecting content transmitted. In this case, the client 100 can use processing means such as a cable card (or Point of Deployment (POD)) or a downloadable conditional access system (DCAS), for the conditional access or protecting content.

In addition, the client 100 can use a bi-directional service through a network. In this case, the client 100 can perform or function as the CP 10. And, the SP 20 can transmit it to other client.

In FIG. 1, CP 10 and/or SP 20 can be a server providing service which specifies below in the disclosure. In this case, the server can include the NP 30, if necessary. Even though not specified in the disclosure, service or service data can include not only service or application received from the external server but also an internal service or application as above-mentioned. This service or application is defined service data or application data for the client 100 based on the Web OS.

FIG. 2 is a block diagram showing a digital device according to one embodiment of the present invention.

In the disclosure, the digital device can correspond to the client 100 shown in FIG. 1.

The digital device 200 can include a network interface 201, a TCP/IP (Transfer Control Protocol/Internet Protocol) manager 202, a service delivery manager 203, an SI (System Information, Service Information or Signaling Information) decoder 204, a demultiplexer 205, an audio decoder 206, a video decoder 207, a display AN (Audio/Video) and OSD (On Screen Display) module 208, a service control manager 209, a service discovery manager 210, a SI & metadata database (DB) 211, a metadata manager 212, a service manage 213, a UI (User Interface) manager 214, etc.

The network interface 201 can receive or transmit IP (Internet Protocol) packets or IP datagrams (hereinafter, referred as IP packets) through a network accessed. As an example, the network interface 201 can receive service, application, content, etc., from the SP 20 of FIG. 1 through the network.

The TCP/IP manager 202 is involved in packet delivery of IP packets transmitted to the digital device 200 and IP packets transmitted from the digital device 200 between a source and a destination. The TCP/IP manager 202 may classify received packets according to an appropriate protocol and output the classified packets to the service delivery manager 205, the service discovery manager 210, the service control manager 209, and the metadata manager 212, etc.

The service delivery manager 203 can control received service data. For example, the service delivery manager 203 can use Real-Time Protocol/Real-Time Control Protocol (RTP/RTCP) to control real-time streaming data. If the real-time streaming data is transmitted using the RTP, the service delivery manager 203 can parse a received real-time streaming data packet, transmitted based on the RIP, and transmits the parsed data packet to the demultiplexer 205 or store the parsed data packet in the SI & metadata DB 211 under the control of the service manager 213. The service delivery manager 203 can provide feedback of the network reception information to the server based on the RTCP.

The demultiplexer 205 can demultiplex audio data, video data, SI data from a received packet and transmit the demultiplexed data to each of the audio/video decoder 206/207 and the SI decoder 204.

The SI decoder 204 can decode the demultiplexed SI data such as program specific information (PSI), program and system information protocol (PSIP), digital video broadcast-service information (DVB-SI), digital television terrestrial multimedia broadcasting/coding mobile multimedia broadcasting (DTMB/CMMB), etc. The SI decoder 204 can store the decoded SI data in the SI & metadata DB 211. The SI data stored in the SI & metadata DB 211 can be read and extracted by a component which requires the SI data according to user request, for example.

The audio decoder 206 and the video decoder 207 can decode the demultiplexed audio and video data, respectively. The decoded audio data and video data can be provided to the user through the display unit 208.

The application manager can include the service manager 213 and the UI manager 214, for example. The application manager can perform a function of the controller of the digital device 200. In other words, the application manager can administrate the overall state of the digital receiver 200, provides a UI, and manage other mangers.

The UI manager 214 can provide a graphic user interface (GUI)/UI for the user using OSD, etc. And, the UI manager 214 can receive a key input from the user and perform an operation of the device in response to the received key input. For example, the UI manager 214 can transmit a key input signal to the service manager 213 if the key input signal of selecting a channel is received from the user.

The service manager 213 can control service-related managers such as the service delivery manager 203, the service discovery manager 210, the service control manager 209, and the metadata manager 212.

The service manager 213 can generate a channel map and control a channel selection using the generated channel map according to the received key input from the UI manager 214. The service manager 213 can receive service information from the SI decoder 204 and set audio/video PID (packet identifier) of a selected channel to the demultiplexer 205. The set audio/video PID can be used for the demultiplexing procedure. Accordingly, the demultiplexer 205 can filter the audio data, video data and SI data using the PID (PID filtering or section filtering.)

The service discovery manager 210 can provide information required to select a service provider that provides a service. Upon receipt of a signal for selecting a channel from the service manager 213, the service discovery manager 210 discovers or searches a service based on the received signal.

The service control manager 209 can select and control a service. For example, the service control manager 209 can use perform service selection and control using IGMP or real time streaming protocol (RTSP) when the user selects a live broadcast service, and using RTSP when the user selects a VOD service. The RTSP can provide a trick mode for the real-time streaming. Also, the service manager 213 can initialized and manage a session through the IMS (IP Multimedia Subsystem) gateway 250 using IMS and SIP (Session Initiation Protocol.) The above protocols are just an example and other protocols can be used depending on an implementation.

The metadata manager 212 can manage metadata regarding services and store metadata in the SI & metadata DB 211.

The SI & metadata DB 211 can store SI data decoded by the SI decoder 204, metadata managed by the metadata manager 212, and information required to select a service provider, which is provided by the service discovery manager 210. In addition, the SI & metadata DB 211 can store system set-up data, etc.

The SI & metadata DB 211 can be implemented using a Non-Volatile RAM (NVRAM) or a Flash memory, and the like.

An IMS gateway 250 can be a gateway that collects functions required to access IPTV services based on an IMS.

FIG. 3 is a block diagram illustrating the digital device according to another embodiment of the present invention.

FIG. 2 explained above refers to a standing device as according to an embodiment of the digital device, but FIG. 3 refers to a mobile device as another embodiment of the digital device

With reference to FIG. 3, the mobile terminal 300 can include a wireless communication unit 310, an A/V input unit 320, an user input unit 330, a sensing unit 340, an output unit 350, a memory 360, an interface unit 370, a controller 380, and a power supply unit 390.

Each element is explained in detail as follows.

The wireless communication unit 310 typically includes one or more components which permit wireless communication between the mobile terminal 300 and a wireless communication system or network within which the mobile terminal 300 is located. For instance, the wireless communication unit 310 can include a broadcast receiving module 311, a mobile communication module 312, a wireless Internet module 313, a short-range communication module 314, and a position-location module 315.

The broadcast receiving module 311 receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. At least two broadcast receiving modules 311 can be provided in the mobile terminal 300 to facilitate simultaneous reception of at least two broadcast channels or broadcast channel switching.

The broadcast associated information includes information associated with a broadcast channel, a broadcast program, or a broadcast service provider. Furthermore, the broadcast associated information can be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module 312.

The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) and an electronic service guide (ESG).

The broadcast receiving module 311 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By non-limiting example, such broadcasting systems may include digital video broadcasting-Terrestrial (DVB-T), DVB-Satellite (DVB-S), DVB-Handheld (DVB-H), DVB-Convergence of Broadcasting and Mobile Services (DVB-CBMS), Open Mobile Alliance Broadcast (OMA-BCAST), the data broadcasting system known as media forward link only (MediaFLO™) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module 311 can be configured to be suitable for other broadcasting systems as well as the above-noted digital broadcasting systems.

The broadcast signal and/or broadcast associated information received by the broadcast receiving module 311 may be stored in a suitable device, such as the memory 360.

The mobile communication module 312 transmits/receives wireless signals to/from one or more network entities (e.g., a base station, an external terminal, and/or a server) via a mobile network such as GSM (Global System for Mobile communications), CDMA (Code Division Multiple Access), or WCDMA (Wideband CDMA). Such wireless signals may carry audio, video, and data according to text/multimedia messages.

The wireless Internet module 313 supports Internet access for the mobile terminal 300. This module may be internally or externally coupled to the mobile terminal 300. The wireless Internet technology can include WLAN (Wi-Fi), Wibro, Wimax, or HSDPA.

The short-range communication module 314 facilitates relatively short-range communications. Suitable technologies for implementing this module include RFID, IrDA, UWB, as well as the networking technologies commonly referred to as Bluetooth™ and ZigBee™, to name a few.

The position-location module 315 identifies or otherwise obtains the location of the mobile terminal 100. According to one embodiment, this module may be implemented with a global positioning system (GPS) module. The GPS module 315 can precisely calculate current 3-dimensional position information based on at least longitude, latitude or altitude and direction (or orientation) by calculating distance information and precise time information from at least three satellites and then applying triangulation to the calculated information. Location information and time information are calculated using three satellites, and errors of the calculated location position and one or more time information are then amended (or corrected) using another satellite. In addition, the GPS module 315 can calculate speed information by continuously calculating a real-time current location.

With continued reference to FIG. 3, the A/V input unit 320 is configured to provide audio or video signal input to the mobile terminal 300. As shown, the A/V input unit 320 includes a camera 321 and a microphone 322. The camera 321 receives and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. Furthermore, the processed image frames can be displayed on the display 351.

The image frames processed by the camera 321 can be stored in the memory 360 or can be transmitted to an external recipient via the wireless communication unit 310. Optionally, at least two cameras 321 can be provided in the mobile terminal 300 according to the environment of usage.

The microphone 322 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electronic audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 312 in a call mode. The microphone 322 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.

The user input unit 330 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, and a jog switch.

The sensing unit 340 provides sensing signals for controlling operations of the mobile terminal 300 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 340 may detect an open/closed status of the mobile terminal 100, the relative positioning of components (e.g., a display and keypad) of the mobile terminal 300, a change of position (or location) of the mobile terminal 300 or a component of the mobile terminal 300, a presence or absence of user contact with the mobile terminal 300, and an orientation or acceleration/deceleration of the mobile terminal 300. As an example, a mobile terminal 300 configured as a slide-type mobile terminal is considered. In this configuration, the sensing unit 340 may sense whether a sliding portion of the mobile terminal is open or closed. According to other examples, the sensing unit 340 senses the presence or absence of power provided by the power supply unit 390, and the presence or absence of a coupling or other connection between the interface unit 370 and an external device. According to one embodiment, the sensing unit 340 can include a proximity sensor 341.

The output unit 350 generates output relevant to the senses of sight, hearing, and touch. Furthermore, the output unit 350 includes the display 351, an audio output module 352, an alarm unit 353, a haptic module 354, and a projector module 355.

The display 351 is typically implemented to visually display (output) information associated with the mobile terminal 300. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a UI or GUI which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 300 is in a video call mode or a photographing mode, the display 351 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.

The display module 351 may be implemented using known display technologies. These technologies include, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 300 may include one or more of such displays.

Some of the displays can be implemented in a transparent or optical transmittive type, i.e., a transparent display. A representative example of the transparent display is the TOLED (Transparent OLED). A rear configuration of the display 351 can be implemented as the optical transmittive type as well. In this configuration, a user can see an object located at the rear of a terminal body on a portion of the display 351 of the terminal body.

At least two displays 351 can be provided in the mobile terminal 300 in accordance with one embodiment of the mobile terminal 300. For instance, a plurality of displays can be arranged to be spaced apart from each other or to form a single body on a single face of the mobile terminal 300. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 300.

If the display 351 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) are configured as a mutual layer structure (hereinafter called ‘touch screen’), the display 351 is usable as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, or a touchpad.

The touch sensor can be configured to convert pressure applied to a specific portion of the display 351 or a variation of capacitance generated from a specific portion of the display 351 to an electronic input signal. Moreover, the touch sensor is configurable to detect pressure of a touch as well as a touched position or size.

If a touch input is made to the touch sensor, a signal(s) corresponding to the touch input is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 380. Therefore, the controller 380 is made aware when a prescribed portion of the display 351 is touched.

A proximity sensor 341 can be provided at an internal area of the mobile terminal 300 enclosed by the touch screen or around the touch screen. The proximity sensor is a sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing (or located) around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor 341 is more durable than a contact type sensor and also has utility broader than the contact type sensor.

For example, the proximity sensor 341 can include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. If the touch screen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of an electric field according to the proximity of the pointer. In this configuration, the touch screen (touch sensor) can be considered as the proximity sensor.

For clarity and convenience of explanation, an action for enabling the pointer approaching the touch screen to be recognized as placed on the touch screen may be named ‘proximity touch’ and an action of enabling the pointer to actually come into contact with the touch screen may named ‘contact touch’. And, a position, at which the proximity touch is made to the touch screen using the pointer, may mean a position of the pointer vertically corresponding to the touch screen when the pointer makes the proximity touch.

The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state). Information corresponding to the detected proximity touch action and the detected proximity touch pattern can be output to the touch screen.

The audio output module 352 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, and a broadcast reception mode to output audio data which is received from the wireless communication unit 310 or is stored in the memory 360. During operation, the audio output module 352 outputs audio relating to a particular function (e.g., call received, message received). The audio output module 352 may be implemented using one or more speakers, buzzers, other audio producing devices, and combinations of these devices.

The alarm unit 353 outputs a signal for announcing the occurrence of a particular event associated with the mobile terminal 300. Typical events include a call received, a message received and a touch input received. The alarm unit 353 can output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be output via the display 351 or the audio output module 352. Hence, the display 351 or the audio output module 352 can be regarded as a part of the alarm unit 353.

The haptic module 354 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 354. The strength and pattern of the vibration generated by the haptic module 354 are controllable. For instance, different vibrations can be output by being synthesized together or can be output in sequence. The haptic module 354 can generate various tactile effects as well as the vibration. For instance, the haptic module 354 may generate an effect attributed to the arrangement of pins vertically moving against a contact skin surface, an effect attributed to the injection/suction power of air though an injection/suction hole, an effect attributed to the skim over a skin surface, an effect attributed to a contact with an electrode, an effect attributed to an electrostatic force, and an effect attributed to the representation of a hot/cold sense using an endothermic or exothermic device. The haptic module 354 can be implemented to enable a user to sense the tactile effect through a muscle sense of a finger or an arm as well as to transfer the tactile effect through direct contact. Optionally, at least two haptic modules 354 can be provided in the mobile terminal 300 in accordance with an embodiment of the mobile terminal 300.

The memory 360 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 300. Examples of such data include program instructions for applications operating on the mobile terminal 300, contact data, phonebook data, messages, audio, still pictures (or photo), and moving pictures. Furthermore, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia file) can be stored in the memory 360. Moreover, data for various patterns of vibration and/or sound output in response to a touch input to the touch screen can be stored in the memory 360.

The memory 360 may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory or XD memory), or other similar memory or data storage device. Furthermore, the mobile terminal 300 can operate in association with a web storage for performing a storage function of the memory 360 on the Internet.

The interface unit 370 may be implemented to couple the mobile terminal 100 with external devices. The interface unit 370 receives data from the external devices or is supplied with power and then transfers the data or power to the respective elements of the mobile terminal 300 or enables data within the mobile terminal 300 to be transferred to the external devices. The interface unit 370 may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, and/or an earphone port.

The identity module is a chip for storing various kinds of information for authenticating a usage authority of the mobile terminal 300 and can include a User Identify Module (UIM), a Subscriber Identity Module (SIM), and/or a Universal Subscriber Identity Module (USIM). A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectible to the mobile terminal 300 via the corresponding port.

When the mobile terminal 300 is connected to an external cradle, the interface unit 370 becomes a passage for supplying the mobile terminal 300 with a power from the cradle or a passage for delivering various command signals input from the cradle by a user to the mobile terminal 300. Each of the various command signals input from the cradle or the power can operate as a signal enabling the mobile terminal 300 to recognize that it is correctly loaded in the cradle.

The controller 380 typically controls the overall operations of the mobile terminal 300. For example, the controller 380 performs the control and processing associated with voice calls, data communications, and video calls. The controller 380 may include a multimedia module 381 that provides multimedia playback. The multimedia module 381 may be configured as part of the controller 380, or implemented as a separate component. Moreover, the controller 380 can perform a pattern (or image) recognizing process for recognizing a writing input and a picture drawing input performed on the touch screen as characters or images, respectively.

The power supply unit 390 provides power required by various components of the mobile terminal 300. The power may be internal power, external power, or combinations of internal and external power.

The controller 470 can generate and output a signal for video or audio output by demultiplexing streams input through the tuner 410, the demodulator 420 or the external device interface 435 or processing demultiplexed signals.

A video signal processed by the controller 470 can be input to the display unit 380 and displayed as an image through the display unit 480. In addition, the video signal processed by the controller 470 can be input to an external output device through the external device interface 435.

An audio signal processed by the controller 470 can be applied to the audio output unit 485. Otherwise, the audio signal processed by the controller 470 can be applied to an external output device through the external device interface 435.

The controller 470 may include a demultiplexer and an image processor, which are not shown in FIG. 4.

The controller 470 can control the overall operation of the digital receiver 300. For example, the controller 470 can control the tuner 410 to tune to an RF broadcast corresponding to a channel selected by the user or a previously stored channel.

The controller 470 can control the digital receiver 400 according to a user command input through the user input interface 450 or an internal program. Particularly, the controller 470 can control the digital receiver 400 to be linked to a network to download an application or application list that the user desires to the digital receiver 400.

For example, the controller 470 may control the tuner 410 to receive a signal of a channel selected in response to a predetermined channel selection command received through the user input interface 450. In addition, the controller 470 may process a video, audio or data signal corresponding to the selected channel. The controller 470 may control information on a channel selected by the user to be output with a processed video or audio signal through the display unit 480 or the audio output unit 485.

In addition, the remote controller 500 can receive audio, video or data signal output from the user input interface 350 and display the received signal or output the same as audio or vibration.

The above-mentioned digital device 400 can be a digital broadcast receiver which is capable of processing a digital broadcast signal of a fixed or mobile ATSC method, or a digital broadcast signal of a DVB method.

Some of the components shown in FIG. 2 may be omitted or a component (not shown in FIG. 2) may be added as required. The digital receiver according to the present invention may not include the tuner and the demodulator, differently from the digital receivers shown in FIGS. 2 and 4, and may receive content through the network interface or the external device interface and reproduce the content.

FIG. 5 is a block diagram illustrating the detailed configuration of each of controllers of FIGS. 2 to 4 according to one embodiment of the present invention.

The digital receiver according to the present invention may include a demultiplexer 510, an image processor 520, an OSD generator 540, a mixer 550, a frame rate converter (FRC) 555, and a 3D formatter (or an Output formatter) 560.

The demultiplexer 510 can demultiplex an input stream signal into an MPEG-2 TS image, an audio signal and a data signal, for example.

The image processor 420 can process a demultiplexed image signal using a video decoder 525 and a scaler 535.

The video decoder 525 can decode the demultiplexed image signal and the scaler 535 can scale the resolution of the decoded image signal such that the image signal can be displayed.

The video decoder 525 can support various standards. For example, the video decoder 525 can perform a function as an MPEG-2 decoder when the video signal is coded in an MPEG-2 standard. The video decoder 525 can perform a function as a H.264 decoder when the video signal is coded in a digital multimedia broadcasting (DMB) method or the H.264 standard method.

The image signal decoded by the image processor 520 may be input to the mixer 550.

The OSD generator 540 may generate OSD data automatically or according to user input. For example, the OSD generator 540 may generate data to be displayed on the screen of an output unit in the form of an image or text on the basis of a control signal of a user input interface. OSD data generated by the OSD generator 540 may include various data such as a UI image of the digital receiver, various menu screens, widget, icons, and information on ratings. The OSD generator 540 can generate a caption of a broadcast image or data for displaying EPG based broadcast information.

The mixer 550 may mix the OSD data generated by the OSD generator 540 and the image signal processed by the image processor 520. The mixer 550 may provide the mixed signal to the 3D formatter 560. By mixing the decoded image signal and the OSD data, OSD may be overlaid on a broadcast image or external input image.

The frame rate converter (FRC) 555 may convert a frame rate of input video. For example, the frame rate converter 555 can convert the frame rate of an input 60 Hz video to a frame rate of 120 Hz or 240 Hz, according to an output frequency of the output unit. The frame rate converter 555 may be bypassed when frame conversion is not executed.

The 3D formatter 560 may change the output of the frame rate converter 555, which is input thereto, into a form suitable for the output format of the output unit. For example, the 3D formatter 560 can output an RGB data signal. In this case, this RGB data signal can be output according to low voltage differential signaling (LVDS) or mini-LVDS. When a 3D image signal output from the frame rate converter 555 is input to the 3D formatter 560, the 3D formatter 560 can format the 3D image signal such that the 3D image signal is matched to the output format of the output unit, to thereby support a 3D service.

An audio processor (not shown) may audio-process a demultiplexed audio signal. The audio processor (not shown) can support various audio formats. For example, when audio signals are encoded in MPEG-2, MPEG-4, advanced audio coding (AAC), high efficiency-AAC (HE-AAC), AC-3 and bit sliced audio coding (BSAC) formats, the audio processor (not shown) can include decoders corresponding to the formats to process the audio signals.

Furthermore, the audio processor (not shown) can control base, treble and volume.

In addition, a data processor (not shown) can process a demultiplexed data signal. For example, when a demultiplexed data signal is encoded, the data processor (not shown) can decode the encoded demultiplexed data signal. Here, the encoded data signal may be EPG information including broadcast information such as the start time and end time (or duration) of a broadcast program which is broadcast through each channel.

Meanwhile, the above-mentioned digital device, as an embodiment according to the present invention, each component can be integrated, added or omitted according to a capability of the digital device which is actually implemented. That is, if necessary, at least two components are united into a single component or a single component is divided into at least two components. Also, a function performed by each block explains an embodiment of the present invention, the specific operation or device is not limited to a scope of the present invention.

Meanwhile, the digital device can be an image signal processing device for performing a signal of an input image or an image stored in the device. Other example of the image signal device can be a STB which does not include the display unit 480 and the audio output unit 485 shown in FIG. 4, a DVD player, a Blu-ray player, a game device, a computer, etc.

FIG. 6 is a diagram illustrating an input unit connected to each of the digital devices of FIGS. 2 to 4 according to one embodiment of the present invention.

To execute various operations for implementing the present invention according to embodiments, various user interface devices (UIDs) which can communicate with a digital receiver 600 in a wired/wireless manner can be used as remote controllers.

UIDs can include a mobile device (e.g., a smart phone, a tablet PC, and the like), a magic remote controller 620 and a remote controller 630 equipped with a keyboard and a touch pad in addition to a general remote controller 610.

The remote controllers can use various communication protocols such as Bluetooth, RFID, IrDA, UWB, ZigBee, DLNA, etc.

The magic remote controller 620 may include a gyro sensor mounted therein to sense vibration of a user's hand or rotation. That is, the magic remote controller 620 can move a pointer according to up, down, left and right motions of the user such that the user can easily execute a desired action, for example, easily control a channel or a menu.

The remote controller 630 including the keyboard and touch pad can facilitate text input through the keyboard and control of movement of a pointer and magnification and reduction of a picture or video through the touch pad.

The keyboard 630 have been implemented so that it is similar to a keyboard of a PC in order to conveniently input text because the traditional remote control 610 is not sufficient enough to control the digital device 600 since the digital device 600 offers more than just providing broadcast programs as it did before, but has advanced into a intelligent integrated digital device providing web browser, application, SNS and the like.

Meanwhile, the control means such as the remote control 610, the pointing device 620, and the keyboard 630 can, if necessary, include a touchpad to control functions of text input, move the pointer, enlarging/reducing pictures and video clips more conveniently.

The digital device described in the present specification uses Web OS as a platform. Hereinafter, a Web OS based process or algorithm may be performed by the controller of the above-described digital device. The controller includes the controllers of FIGS. 2 to 5 and has wide concepts. Accordingly, hereinafter, a component for processing Web OS based services, applications, content, etc., including software, firmware or hardware in a digital device is referred to a controller.

Such a Web OS based platform may improve development independency and functional extensibility by integrating services, applications, etc. based on a Luna-service bus, for example, and increase application development productivity based on web application framework. In addition, system resources, etc. may be efficiently used via a Web OS process and resource management to support multitasking.

A Web OS platform described in the present specification may be available not only for stationary devices such as PCs, TVs and STBs but also for mobile devices such as cellular phones, smartphones tablet PCs, laptops, and wearable devices.

A software structure for a digital device is a monolithic structure which solves conventional problems depending on markets, is a single process and closed product based on multi-threading, and has difficulties in terms of external applications. In pursuit of new platform based development, cost innovation via chipset replacement and UI application and external application development efficiency, layering and componentization are performed to obtain a 3-layered structure and an add-on structure for an add-on, a single source product and an open application. Recently, modular design of a software structure has been conducted in order to provide a web open application programming interface (API) for an echo system and modular architecture of a functional unit or a native open API for a game engine, and thus a multi-process structure based on a service structure has been produced.

FIG. 7 is a diagram illustrating Web OS architecture according to one embodiment of the present invention.

The architecture of a Web OS platform will now be described with reference to FIG. 7.

The platform may be largely divided into a kernel, a system library based Web OS core platform, an application, a service, etc.

The architecture of the Web OS platform has a layered structure. OSs are provided at a lowest layer, system library(s) are provided at a next highest layer and applications are provided at the highest layer.

First, the lowest layer is an OS layer including a Linux kernel such that Linux is included as an OS of the digital device.

At layers higher than the OS layer, a board support package (BSP)/hardware abstraction layer (HAL) layer, a Web OS core modules layer, a service layer, a Luna-service bus layer and an Enyo framework/native developer's kit (NDK)/QT layer are sequentially provided. At the highest layer, an application layer is provided.

Some layers of the above-described Web OS layered structure may be omitted and a plurality of layers may be combined to one layer and one layer may be divided into a plurality of layers.

The Web OS core module layer may include a Luna surface manager (LSM) for managing a surface window, etc., a system & application manager (SAM) for managing execution and performance status of applications, etc., and a web application manager (WAM) for managing web applications based on WebKit.

The LSM manages an application window displayed on a screen. The LSM may control display hardware (HW) and provide a buffer for rendering content necessary for applications, and compose and output results of rendering a plurality of applications on a screen.

The SAM manages policy according to several conditions of systems and applications.

The WAM is based on Enyo framework, because a Web OS regards a web application as a basic application.

An application may use a service via a Luna-service bus. A service may be newly registered via a bus and the application may detect and use a desired service.

The service layer may include services having various service levels, such as a TV service, a Web OS service, etc. The Web OS service may include a media server, Node.JS, etc. and, in particular, the Node.JS service supports JavaScript, for example.

The Web OS service may be communicated to a Linux process implementing function logic via a bus. This Web OS service is largely divided into four parts, migrates from a TV process and an existing TV to a Web OS, is developed as services which differ between manufacturers, Web OS common services and JavaScripts, and is composed of the Node.js service used via Node js.

The application layer may include all applications supportable by a digital device, such as a TV application, a showcase application, a native application, a web application, etc.

Applications on the Web OS may be divided into a web application, a palm development kit (PDK) application, a Qt Meta Language or Qt Modeling Language (QML) application, etc. according to implementation methods.

The web application is based on a WebKit engine and is performed on WAM runtime. Such a web application is based on Enyo framework or may be developed and performed based on general HTML5, cascading style sheets (CSS) and JavaScripts.

The PDK application includes a native application developed with C/C++ based on a PDK provided for a third party or an external developer. The PDK refers to a set of development libraries and tools provided to enable a third party to develop a native application (C/C++) such as games. For example, the PDK application may be used to develop applications requiring high performance.

The QML application is a Qt based native application and includes basic applications provided along with the Web OS platform, such as card view, home dashboard, virtual keyboard, etc. QML is a markup language of a script format, not C++.

The native application is an application which is developed and compiled using C/C++ and is executed in the binary form and has an advantage such as high execution speed.

FIG. 8 is a diagram illustrating the architecture of a Web OS device according to one embodiment of the present invention.

FIG. 8 is a block diagram based on a runtime of a Web OS device and is described with reference to the layered structure of FIG. 7.

Hereinafter, a description will be given with reference to FIGS. 7 and 8.

Referring to FIG. 8, services, applications and Web OS core modules are included on a system OS (Linux) and system libraries and communication therebetween may be performed via a Luna-service bus.

Node.js services based on HTML5 such as e-mail, contact or calendar, CSS, JavaScript, etc., Web OS services such as logging, backup, file notify, database (DB), activity manager, system policy, audio daemon (AudioD), update, media server, etc., TV services such as electronic program guide (EPG), personal video recorder (PVR), data broadcasting, etc., CP services such as voice recognition, now on, notification, search, auto content recognition (ACR), contents list browser (CBOX), wfdd, DMR, remote application, download, Sony Philips digital interface format (SDPIF), etc., native applications such as PDK applications, browsers, QML applications, a UI-related TV applications based on Enyo framework and web applications are processed via Web OS core modules such as the above-described SAM, WAM and LSM via the Luna-service bus. The TV applications and the web applications are not necessarily based on Enyo framework or related to UI.

The CBOX may manage metadata and lists of content of external devices such as USB drivers, DLNA devices or Cloud servers connected to a TV. The CBOX may output content listing of various content containers such as USB, DMS, DVR, Cloud server, etc. as an integrated view. The CBOX may display various types of content listings such as pictures, music or video and manage metadata thereof. The CBOX may output content of an attached storage in real time. For example, if a storage device such as a USB is plugged in, the CBOX should immediately output a content list of the storage device. At this time, a standardized method for processing the content listing may be defined. The CBOX may accommodate various connection protocols.

The SAM is used to improve module complexity and extensibility. For example, an existing system manager processes several functions such as system UI, window management, web application runtime and UX constraint processing via one process and thus has high implementation complexity. In order to solve such a problem, the SAM divides main functions and clarifies an interface between functions, thereby decreasing implementation complexity.

The LSM is supported to independently develop and integrate a system UX such as card view, launcher, etc. and to easily cope with change in product requirements. The LSM maximally uses hardware resources to enable multitasking if a plurality of application screens is composed using an app-on-app method and may provide a window management mechanism for 21:9 and a multi-window.

The LSM supports implementation of a system UI based on a QML and improves development productivity. QML UX may easily configure a view using a screen layout and UI components based on MVC and easily develop code for processing user input. An interface between the QML and the Web OS component is achieved via a QML extensibility plug-in and graphic operation of an application may be based on Wayland protocol, luna-service call, etc.

The LSM is an abbreviation for a Luna surface manager and functions as an application window compositor.

The LSM composes and outputs independently developed applications, UI components, etc. on a screen. When components such as recent applications, showcase applications or launcher applications render respective content, the LSM defines an output area, a linkage method, etc. as a compositor. The LSM functioning as a compositor performs processing such as graphic composition, focus management, input events, etc. At this time, the LSM receives event, focus, etc. from an input manager, and a remote controller, a HID such as a mouse and keyboard, a joystick, a game pad, a remote application, a pen touch, etc. may be included as an input manager.

The LSM supports multiple window models and may be simultaneously executed in all applications as a system UI. The LSM may support launcher, recents, setting, notification, system keyboard, volume UI, search, finger gesture, voice recognition (speech to text (STT), text to speech (TTS), natural language processing (NLP), etc.), pattern gesture (camera or mobile radio control unit (MRCU)), live menu, auto content recognition (ACR), etc.

FIG. 9 is a diagram illustrating a graphic composition flow in a Web OS device according to one embodiment of the present invention.

Referring to FIG. 9, graphic composition processing may be performed via a web application manager 910 functioning as a UI process, a WebKit 920 functioning as a web process, an LSM 930 and a graphics manager (GM) 940.

When the web application manager 910 generates web application based graphics data (or application) as a UI process, the generated graphics data is delivered to the LSM if the graphics data is not a fullscreen application. The web application manager 910 receives an application generated by the WebKit 920 in order to share a graphic processing unit (GPU) memory for graphic management between the UI process and the web process and delivers the application to the LSM 930 if the application is not a fullscreen application. If the application is a fullscreen application, the LSM 930 may bypass the application. In this case, the application is directly delivered to the graphics manager 940.

The LSM 930 transmits the received UI application to a Wayland compositor via a Wayland surface and the Wayland compositor appropriately processes the UI application and delivers the processed UI application to the graphics manager. The graphics data received from the LSM 930 is delivered to the graphics manager compositor via the LSM GM surface of the graphics manager 940, for example.

The fullscreen application is directly delivered to the graphics manager 940 without passing through the LSM 930 as described above and is processed in the graphics manager compositor via the WAM GM surface.

The graphics manager processes and outputs all graphics data in the Web OS device and receives and outputs data passing through the above-described LSM GM surface, data passing through a WAM GM surface, and graphics data passing through a GM surface, such as a data broadcasting application or a caption application, on a screen. The function of the GM compositor is equal or similar to the above-described compositor.

FIG. 10 is a diagram illustrating a media server according to one embodiment of the present invention, FIG. 11 is a block diagram illustrating a media server according to one embodiment of the present invention, and FIG. 12 is a diagram illustrating a relationship between a media server and a TV service according to one embodiment of the present invention.

The media server supports execution of a variety of multimedia in a digital device and manages necessary resources. The media server may efficiently use hardware resources necessary for media play. For example, the media server requires audio/video hardware resources for multimedia execution and efficiently manages a resource use status to efficiently use resources. In general, a stationary device having a screen larger than that of a mobile device requires more hardware resources upon multimedia execution and requires high encoding/decoding rate and graphics data transfer rate due to a large amount of data. The media server should perform not only streaming or file playback but also broadcasting, recording and tuning tasks, a task for simultaneously viewing and recording, and a task for simultaneous displaying a sender and a recipient on a screen upon video call. It is difficult for the media server to simultaneously perform several tasks due to restriction in hardware resources such as an encoder, a decoder, a tuner, a display engine, etc. in chipset units. For example, the media server restricts a use scenario or performs processing using user input.

The media server may make system stability robust, and may remove a playback pipeline, in which errors occur during media playback, per pipeline, such that other media play is not influenced even when errors occur. Such a pipeline is a chain for connecting unit functions such as decoding, analysis, output, etc. upon a media playback request, and required unit functions may be changed according to media type, etc.

The media server may have extensibility and may add a new type of pipeline without influencing an existing implementation method. For example, the media server may accommodate a camera pipeline, a video conference (Skype) pipeline, a third-party pipeline, etc.

The media server may process general media playback and TV task execution as separate services because the interface of the TV service is different from that of media playback. The media server supports operation such as “set channel”, “channel up”, “channel down”, “channel tuning” and “record start” in relation to the TV service and support operation such as “play”, “pause” and “stop” in relation to general media playback, that is, supports different operations with respect to the TV service and general media playback and processes the TV service and media playback as separate services.

The media server may control or manage a resource management function. Hardware resource assignment or recovery in a device is conducted by the media server. In particular, the TV service process delivers a task which is being executed and a resource assignment status to the media server. The media server secures resources to execute a pipeline whenever media is executed, allows media execution due to priority (e.g., policy) upon media execution request, and performs resource recovery of another pipeline, based on a resource status of each pipeline. The predefined execution priority and resource information necessary for a specific request are managed by a policy manager and the resource manager communicates with the policy manager to process resource assignment and recovery.

The media server may have identifiers (IDs) for all operations related to playback. For example, the media server may send a command to a specific pipeline based on the ID. The media server may send respective commands to pipelines for playback of two or more media.

The media server is responsible for playing back a HTML5 standard media.

The media server performs a service process of a TV pipeline according to a TV restructuralization range. The media server may be designed and implemented regardless of the TV restructuralization range. If the separate service process of the TV is not performed, the TV may be wholly re-executed when errors occurs in a specific task.

The media server is also referred to as uMS, that is, a micro media server. The media player is a media client and means WebKit for HTML5 video tag, camera, TV, Skype or second screen, for example.

The media server mainly manages micro resources such as a resource manager or a policy manager. The media server also controls playback of web standard media content. The media server may manage pipeline controller resources.

The media server supports extensibility, reliability, efficient resource usage, etc., for example.

In other words, the uMS, that is, the micro media server, manages and controls resource usage for appropriate processing within the Web OS device, such as resources such as cloud game, MVPD (pay service, etc.), camera preview, second screen or Skype, and TV resources. A pipeline is used upon usage of each resource, for example, and the media server may manage and control generation, deletion, use of a pipeline for resource management.

The pipeline may be generated when a media related to a task starts a sequence of request, decoding streaming and parsing such as video output. For example, in association with a TV service and an application, watching, recording, channel tuning, etc. are controlled and performed via pipelines individually generated according to requests thereof with respect to resource usage.

Referring to FIG. 10, a processing structure of a media server will be described in detail.

In FIG. 10, an application or service is connected to a media server 1020 via a Luna-service bus 1010 and the media server 1020 is connected to and managed by pipelines generated via the Luna-service bus 1010.

The application or service includes various clients according to properties thereof and may exchange data with the media server 1020 or the pipeline via the clients.

The clients include a uMedia client (WebKit) for connection with the media server 1020 and a resource manager (RM) client (C/C++), for example.

The application including the uMedia client is connected to the media server 1020 as described above. More specifically, the uMedia client corresponds to the below-described video object, for example, and uses the media server 1020, for video operation by a request, etc.

The video operation relates to a video status and may include all status data related to the video operation, such as loading, unloading, play (playback or reproduction), pause, stop, etc. Such video operations or statuses may be processed by generating individual pipelines. Accordingly, the uMedia client transmits status data related to the video operation to the pipeline manager 1022 in the media server.

The media server 1022 acquires information about resources of the current device via data communication with the resource manager 1024 and requests assignment of resources corresponding to the status data of the uMedia client. At this time, the pipeline manager 1022 or the resource manager 1024 controls resource assignment via data communication with the policy manager 1026 if necessary. For example, if resources to be assigned according to the request of the pipeline manager 1022 are not present or are lacking in the resource manager 1024, resource assignment may be appropriately performed according to priority comparison of the policy manager 1026.

The pipeline manager 1022 requests to generate a pipeline for operation according to the request of the uMedia client from the media pipeline controller 102, with respect to resources assigned according to resource assignment of the resource manager 1024.

The media pipeline controller 1028 generates a necessary pipeline under control of the pipeline manager 1022. As shown, a media pipeline, a camera pipeline, a pipeline related to playback, pause or stop may be generated. The pipeline includes pipelines for HTML5, web CP, Smarthshare playback, thumbnail extraction, NDK, cinema, multimedia and hypermedia information coding experts group (MHEG), etc.

The pipeline may include a service-based pipeline and a URI based pipeline (media pipeline), for example.

Referring to FIG. 10, the application or service including the RM client may not be directly connected to the media server 1020, because the application or service can directly process a media. In other words, if the application or service directly processes a media, the media server may not be used. At this time, for pipeline generation and usage, resource management is necessary and, at this time, a uMS connector is used. When a resource management request for direct media processing of the application or service is received, the uMS connector communicates with the media server 1020 including the resource manager 1024. The media server 1020 also includes a uMS connector.

Accordingly, the application or service may cope with the request of the RM client via resource management of the resource manager 1024 via the uMS connector. The RM client may process services such as native CP, TV service, second screen, flash player, You Tube media source extensions (MSE), cloud game, Skype, etc. In this case, as described above, the resource manager 1024 may manage resources via appropriate data communication with the policy manager 1026 if necessary for resource management.

The URI based pipeline does not directly process the media unlike the above-RM client but processes the media via the media server 1020. The URI based pipeline may include player factory, Gstreamer, streaming plug-in, digital rights management (DRM) plug-in pipelines.

An interface method between the application and the media services is as follows.

An interface method using a service in a web application may be used. In this method, a Luna call method using a palm service bridge (PSB) and a method of using Cordova may be used, in which a display is extended to a video tag. In addition, a method of using HTML5 standard related to a video tag or media element may be used.

A method of using a service in PDK may be used.

Alternatively, a method of using in existing CP may be used. For backward compatibility, plug-in of an existing platform may be extended and used based on Luna.

Lastly, an interface method using a non-Web OS may be used. In this case, a Luna bus may be directly called to perform interfacing.

Seamless change is processed by a separate module (e.g., TVWIN) and refers to a process of first displaying a TV program on a screen without a Web OS before or duration Web OS booting and then performing seamless processing. This is used for the purpose of first providing a basic function of a TV service, for fast response to a power-on request of a user, because a booting time of a Web OS is late. The module is a part of a TV service process and supports seamless change for providing fast booting and a basic TV function, factory mode, etc. The module is responsible for switching from the non-Web OS mode to the Web OS mode.

FIG. 11 shows the processing structure of the media server.

In FIG. 11, a solid box denotes a process component and a dotted box denotes an internal processing module of the process. A solid arrow denotes an inter-process call, that is, a Luna-service call and a dotted arrow denotes notification such as register/notify or data flow.

The service, the web application or the PDK application (hereinafter, referred to as “application”) is connected to various service processing components via a Luna-service bus and is operated or controlled via the service processing components.

A data processing path is changed according to application type. For example, if the application includes image data related to a camera sensor, the image data is transmitted to and processed by a camera processor 1130. At this time, the camera processor 1130 includes a gesture or face detection module and processes image data of the received application. The camera processor 1130 may generate a pipeline via a media server processor 1110 with respect to data which requires use of a pipeline according to user selection or automatically and process the data.

Alternatively, if the application includes audio data, the audio may be processed via an audio processor (AudioD) 1140 and an audio module (PulseAudio) 1150. For example, the audio processor 1140 processes the audio data received from the application and transmits the processed audio data to the audio module 1150. At this time, the audio processor 1140 may include an audio policy manager to determine processing of the audio data. The processed audio data is processed by the audio module 1160. The application or a pipeline related thereto may notify the audio module 1160 of data related to audio data processing. The audio module 1150 includes advanced Linux sound architecture (ALSA).

Alternatively, if the application includes or processes (hereinafter, referred to as “includes”) content subjected to DRM, the content data is transmitted to a DRM service processor 1160 and the DRM service processor 1170 generates a DRM instance and processes the content data subjected to DRM. The DRM service processor 1160 is connected to a DRM pipeline in a media pipeline via a Luna-service bus, for processing of the content data subjected to DRM.

Hereinafter, processing of an application including media data or TV service data (e.g., broadcast data) will be described.

FIG. 12 shows the media server processor and the TV service processor of FIG. 11 in detail.

Accordingly, a description will be given with reference to FIGS. 11 and 12.

First, if the application includes TV service data, the application is processed by the TV service processor 1120/1220.

The TV service processor 1120 includes at least one of a DVR/channel manager, a broadcast module, a TV pipeline manager, a TV resource manager, a data broadcast module, an audio setting module, a path manager, etc., for example. In FIG. 12, the TV service processor 1220 may include a TV broadcast handler, a TV broadcast interface, a service processor, TV middleware (MW), a path manager and a BSP (NetCast). The service processor may mean a module including a TV pipeline manager, a TV resource manager, a TV policy manager, a USM connector, etc., for example.

In the present specification, the TV service processor may have the configuration of FIG. 11 or FIG. 12 or a combination thereof. Some components may be omitted or other components (not shown) may be added.

The TV service processor 1120/1220 transmits DVR or channel related data to a DVR/channel manager and transmits the DVR or channel related data to the TV pipeline manager to generate and process a TV pipeline, based on attribute or type of the TV service data received from the application. If the attribute or type of the TV service data is broadcast content data, the TV service processor 1120 generates and processes a TV pipeline via the TV pipeline manager, for processing of the data via a broadcast module.

Alternatively, a JavaScript standard object notation (json) file or a file written in c is processed by the TV broadcast handler and transmitted to the TV pipeline manager via a TV broadcast interface to generate and process a TV pipeline. In this case, the TV broadcast interface may transmit the data or file passing through the TV broadcast handler to the TV pipeline manager based on TV service policy and refer to the data or file upon generating a pipeline.

The TV pipeline manager generates one or more pipelines according to a request for generation of a TV pipeline from the processing module or manager of the TV service processor, under control of the TV resource manager. The TV resource manager may be controlled by the TV policy manager, in order to request a resource assignment status for a TV service according to a request for generation of a TV pipeline of the TV pipeline manager, and may perform data communication with the media server processor 1110/1210 via a uMS connector. The resource manager in the media server processor 1110/1210 sends the resource assignment status for the TV service according to the request of the TV resource manager. For example, if the resource manager in the media server processor 1110/1210 determines that the resources for the TV service are already assigned, the TV resource manager may be notified that assignment of all resources is completed. At this time, the resource manager in the media server processor may remove a predetermined TV pipeline according to a predetermined criterion or priority of TV pipelines already assigned for the TV service along with notification and request generation of a TV pipeline for the requested TV service. Alternatively, the TV resource manager may appropriately remove a TV pipeline or may add or newly establish a TV pipeline according to a status report of the resource manager in the media server processor 1110/1210.

The BSP supports backward compatibility with an existing digital device.

The generated TV pipelines may appropriately operate under control of the path manager in the processing procedure. The path manager may determine or control the processing path or procedure of the pipelines in consideration of the TV pipeline in the processing procedure and the operation of the pipelines generated by the media server processor 1110/1210.

Next, if the application includes media data, not TV service data, the application is processed by the media server processor 1110/1210. The media server processor 1110/1210 includes a resource manager, a policy manager, a media pipeline manager, a media pipeline controller, etc. As pipelines generated under control of the media pipeline manager and the media pipeline controller, a camera preview pipeline, a cloud game pipeline, a media pipeline, etc. may be generated. The media pipeline may include streaming protocol, auto/static gstreamer, DRM, etc. and the processing flow thereof may be determined under control of the path manager. For a detailed description of the processing procedure of the media server processor 1110/1210, refer to the description of FIG. 10 and a repeated description will be omitted.

In the present specification, the resource manager in the media server processor 1110/1210 may perform resource management to a counter base, for example.

Hereinafter, diverse embodiment(s) of the digital device according to the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 13 illustrates a detailed block view showing configuration modules of a digital device according to another embodiment of the present invention. Referring to the above-described FIGS. 1 to 12, some of the modules of the digital device of FIG. 13 may be added or modified (or varied), and the scope of the present invention will not be decided only by the elements described in FIG. 1 to FIG. 13, and, by principle, the scope of the present invention should be interpreted based upon the appended claims of the present invention. As shown in FIG. 13, the digital device (1300) according to an embodiment of the present invention is configured by including a receiving unit (1310), a communication module (1320), a display module (1330), and a controller (1340), and so on.

Such wired/wireless network may include all types of communication networks that are currently supported and that will be supported in the future by a communication standard, and one or more communication protocols for the same may also be supported. Such wired/wireless network may be configured by networks for a wired connection and a communication standard and protocol for the same, such as a USB, a CVBS, a component, an S-video (analog), a DVI, an HDMI, an RGB, a D-SUB, and so on, and configured by networks for a wireless connection and a communication standard and protocol for the same, such as Bluetooth, RFID, IrDA, UWB, ZigBee, DLNA, WLAN (Wi-Fi), Wibro, Wimax, HSDPA, LTE/LTE-A, Wi-Fi Direct, and so on.

The display module (1330) may display at least one or more content. When recommended content data are received through the communication module (1320), the display module (1330) may display a recommended content page, which is processed by using the recommended content data, on a screen. The display module (1330) may correspond to the display (480), which is described in FIG. 4.

The controller (1340) performs a function of managing overall functions of at least one or more modules shown in FIG. 13, such as the receiving unit (1310), the communication module (1320), and the display module (1330), and so on. Respectively, this will be described in more detail later on with reference to FIGS. 14 to 24.

FIG. 14 and FIG. 15 illustrate examples of outputting a recommended content page from the digital device according to an embodiment of the present invention.

A controller of the digital device (1400) according to an embodiment of the present invention may perform control operations, so as to receive a Recommended Content Page Output Request signal, to receive a most recently updated version of Recommended Content Page data through a cloud server, and to display the Recommended Content Page received from the cloud server.

The Recommended Content Page may include a first window (or a first section) including broadcast content information, and a second window (or a second section) including VOD content information.

The first window and the second window may include thumbnail images of each content.

The signal for outputting Recommended Content Page may include a signal configured to select a recommended content page icon from a Home screen and an identical key signal, which is received from an external inputting means for a predetermined period of time or more.

The cloud server may store viewing history data (or viewing record data) of broadcast programs and VOD contents viewed by the user through the digital device during a predetermined period of time.

The broadcast content information and the VOD content information, which are included in the recommended content page, may include the same category information as the broadcast programs and VOD contents included in the viewing history data.

Additionally, when the controller receives a signal pointing the first window through a pointer, the controller may perform control operations so as to display channel information of a broadcast program, broadcasting station title information, title information of a broadcast program, and a progress-bar.

Moreover, when the controller receives a signal pointing the first window through the pointer, the controller may perform control operations so as to display images of a broadcast program, which is being broadcasted in real-time, through the first window.

Furthermore, when the controller receives a signal selecting the first window, the controller may perform control operations so as to expand and display the first window and to display supplemental information of a broadcast program included in the first window along with the respective thumbnail image.

Additionally, when the controller receives a signal pointing the second window through the pointer, the controller may perform control operations so as to display title information of a VOD content, viewer preference information, total playing time (or total running time) information, playback request icon, and supplemental information output request icon of the respective VOD content.

Additionally, when the controller receives a signal selecting the playback request icon, the controller may perform control operations so as to display a CP application list, which includes information on at least one or more CP (Content Provider) application providing the VOD content included in the second window.

Moreover, when the controller receives a signal selecting a specific CP application from the CP application list, the controller may perform control operations so as to execute the selected CP application and to play (or playback) the respective VOD content.

For example, as shown in FIG. 14, the controller of the digital device (1400) according to an embodiment of the present invention may receive a pointer (1420) movement signal from an external inputting means (1410) and may receive a signal selecting a recommended content page icon (1430) by using the pointer (1420).
